Specification of Letters Patent. Application filed Kovember 19;

Patented'Dec. 30,1913. 1 12. Serial no. 732,244.

ToaZZ whomit may concermm Bait known that 1}, GERALQG. GRLFFIN,2L

citizen of'the United States, and a resident of thecity of New York,borough of Mane,

hatt-an, in the county and. State. of New York, have invented. a new andImproved Confetti-Machine, of which, the following isa full, clear, andexact description.

My invention relates to. an improvement. in apparatus for makingconfetti, and the object thereof is to devise a simple and etfir cientmechanism bymeans ofi which a number of sheets of paper Or cardboard canbe divided into. a number ofsmall pieces of regular shape, with littleor no waste. of the material employed.

Reference is, to be had to the. accompanying drawings forming. a part ofthis specification, in which the same characters of reference indicatethe same parts in. all the views.

Figure 1' is a side elevation of my machine, Fig. 2 is a horizontalsection on the line 22 of Fig. 1; Fig. 3 is a sectional view on the line33 of Fig. 1, looking in. the direction. of the arrow; Fig. 4 1s asectional view on the line l4 of F1g. 3-, looking in the direction ofthe arrow; Fig. 5 is a planview of a detail, showing the manner in.

which the operating levers are connected; and Fig. 6 is a sectional viewshowing the parts illustrated at the right of Fig. 4:, the plane ofsection being behind the plane on which Fig. 4 is taken.

My confetti machine comprises a framework 1 which can be provided withperforated lugs 2 to enable it tobe secured by bolts 3 to a support, andthis frame carries a plate 4 having a number of perforations 5 arrangedin diagonally-extending intersecting rows. These openings give passageto plunger-s and guide them for reciprocations in fixed paths, whichplungers pass through alined apertures in a movable plate 7, and in theoperation of'my machine the paper to be divided is placed upon the plate4, the guiding plate 7 loweredto hold the paper in position, and theplungers operated to punch disks from the paper, and force these disksthrough the apertures 5, allowing them to drop into a suitablereceptacle beneath the plate 4.

The stamping plungers 6 are operated by means of spindles 8, onwhich aremounted:

Q the machine every observer. will: have with operating arms 13connection. This link an operating shaft 16 resting in bearings 17operating. shaft 16, There will of course eccentrics 9. surrounded bythe upper ends of'theplungers 6. When. the spindles are turned, theeccentrics of course turn with themand move the spindles downward orupward.

The. number of the. spindles 8, their relat-ion to one another, and alsotheirmanner connection with the plungers 6 may be varied toa,considerable extent without departing from the spirit of this invention,but for the. sake of it will. be seen. that these spindles are arrangedvin two rows or layers one above the illustration from Fig. 1

other, the spindles of the upper layer being staggered; with respect tothe spindles of the lower, and on v each side. of the framework of otherspindle has a squared end 12' which. projects out beyondthe. side; thusbeginning at the left, the first .spindle in the upper row will have asquared end and project from the far side of the framework, while thesecond spindle on the upper row will have a. squared end 12 whichprojects from the side which. is near to the In the lower row the firstspindle a squared end which projects to ward. the observer, and thesecond spindle a squared end which projects from the side of theframework away from the observer. On 1 each side of the machine theprojecting squared ends of thespindles will be provided which arepivotally secured between upper and lower pairs of links lt, these upperand lower pairs of links beingsecured at their right ends to a masterlink15, by means of a bolt and slot 15 is mounted upon formed on theframework of the machine, and operated by means of levers 18 j oined' attheir outer ends by means of a handle bar 19. It will be understood thatthe upper and lower pairs of links 14 extend along each of the sides ofthe machine, s0 that all of the spindles 8 will be connected to the tobe actuated thereby. be two links 15, one for the links 14 at one sideof the machine and the other for the links let on the opposite side.

The staggered arrangement ofthe spindles gives room for the plungersconnected to the Each. of thesev eccentrics is astrap10, and thesestraps have pro ectingarms l1, which are bolted to.

upper row to pass down between the spindles on the lower row, and bythis arrangement I can employ and utilize the largest possible number ofplungers 6 within a given space. It is obvious that the spindles may beplaced in four or more rows, should it be desired to get a longereccentric sweep of the spindles.

The guide plate 7, which has apertures in line with the apertures 5, hasbolts 20 at its corners, projecting through the ends of the machine, andmoving in slots formed in the framework 1. These bolts 20 are secured toarms 21 having spaced projections 22, between which rotates a cam 23,this cam being mounted on the operating shaft 16. There will be four ofthese cams, and four arms 21, two at one end and two at the other, andthe two cams 23 at the rear of the machine, shown at the left in Fig. 1,will be mounted upon a shaft similar to the shaft 16, and connected bylinks 24, which are pivoted by bolts to the lower pairs of links 14 oneither side of the machine, so that when the levers 18 are operated, andthe plungers depressed, the guide plates 7 will be depressed with them.The plate 4 is also provided with a handle 26, and guide lugs 27 alongthe sides. It moves upon guides or ribs 28 located below the plate andextending along the sides of the framework.

Passing through the rear of the framework 1 at the level of the topsurface of the plate 4 are plungers or rods 29 pivotally secured to thestraps 30, and eccentrics 31 mounted upon a spindle 32 carried inbearings 33, and operated by a lever 34. These plungers 29 move thesheets of paper laterally on the plate 4 a predetermined distance andkeep them spaced a suitable distance from the rear wall of the framework1.

In operation, the plate 4 may be with drawn by means of the handle 26,and a suitable number of sheets of paper or cardboard laid on itssurface, between the lugs 27. Preferably these sheets will be of such asize as to fit the plate, extending over the whole distance between theside lugs 27, and from the rear edge of the plate nearly up to the edgeof the first row of apertures to the plate along the front edge. Theplate is then pushed back until the inner edge strikes against the rearwall of the framework, the plungers or rods 29 being withdrawn by thelever 34 until they project no farther than the inner edge of the plateadjacent the first row of holes, as shown in Figs. 2 and 4. In thisposition the plungers 29 project inside of the framework 1 but slightly,and when the plate 4 is pushed in as far as it will go, the sheets ofpaper will engage the plungers when the plate comes to a stop. This isaccomplished by arranging the sheets up to the inner edge of the plate 4when the sheets are placed in position. The levers 18 are now drawnforward,

moving down the guide plate 7 to press upon the sheets and clamp thesame firmly upon the plate 4, and further movement of this lever nowcauses the plungers 6 to make their working stroke and punch pieces ofpaper in the form of disks through the holes 5 in the plate 4. Thesepieces of course will correspond in shape to the shape of the openings 5and the cross-section of the plungers passing through the openings 5.

The shape of the cam 23 will be such that it will move the plate 7downward before the plungers engage the sheets, and hold it down untilthe plungers have been withdrawn. It therefore serves as a stripperplate also. In this way the crumpling of the paper or cardboard isavoided. The perforated sheets are then pushed toward the front edge ofthe plate until the front edge of the sheets almost coincides with thefront edge, and covers the front row of holes 5, that is, the frontedges of the sheets are moved from a point or line indicated at 35 onFig. 4, where they were located during the first operation, the requireddistance to the right of this point. This will bring the unperforatedsections of the sheets in position to cover the holes 5, so that thesheet can be further divided.

The above operation of moving the sheets is effected by means of theplungers 29. Preferably the diameter of the holes and plungers will beabout five-sixteenths of an inch, and the space between the holes 5 willnot be greater than a quarter of an inch measured across or lengthwiseof the sheets. The lever 18 is now operated as before, pulling the sameto the right, causing the plate 7 to clamp the sheets against the plate,and the plungers 6 to stamp another quantity of sections from thematerial of which the sheets are composed. This completes the divisionof the sheet into a number of small particles, and practically none ofthe material is lost or wasted.

From the above description it will be seen that but two operations arenecessary in order to make the confetti, and these are effected in quicksuccession after the sheets have once been put in place on the plate 4.It is only necessary to stop for an instant after the first workingmovement of the plunger 6 to manipulate the lever 34 to cause theperforated sheets to take the proper position for the next operation,and in this way large quantities of confetti can be made in acomparatively short time at a very small expenditure of labor or effort.Of course the machine can be operated by mechanical power if desired.

I wish to have it understood that the above description isillustrativeonly, and that I do not care to be limited to the exact details thereof,but wish to reserve to myself the right to make whatever changes in theshape, size and arrangement of the parts fairly fall within the scopeand spirit of my invention.
